BATH-TU SPECIFICATION forming part of Letters 'Patent No. 493,194, dated March 7, 1893.

Application filed August 31, 1892'. Serial No. 444,651. (No motleLl To all whom it may concern,.-

Be it known that we, HERMAN C. STIFEL, residing at the city of St. Louis, State of Missouri, and FRANCIS J. TORRANCE and OSCAR F. GRANT, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, citi'- zens of the United States, have invented certain new and useful Improvements in Binh- 'l`ubs; and we do hereby declare the fol ow- ;o ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to bath tubs, and particularly to cast iron tubs and the water suppliesthereof, and has forits object, the provision of novel means for supplying the tubs with water and for keeping the inner sides or surfaces of thewalls clean, without zo the necessity of scrubbing or removingthe accumulations by hand.

The invention consists in combining with a bath tub, a hollow metallic rim, conforming in shape and ,dimensions to the wooden rims :5 usually applied, and in constructing and adapt-ing the said hollow rim for use as a water conduit, taking its supply from the hot and cold waterpipes adjacent to the tub, and conveying the same to the interior of the tub go through small jet openings formed in the hollow rim close to the walls of the tub.

The hollow, water conveying rim, constructed according to the present invention serves the double purpose of an ornamental rim, cov- ;5 ering and concealing the unfinished ange around the upper edge of the tub, and a water supply, leading the water of uniform ternperature to all parts of the tub and under such conditions asl will prevent the formation of o unsanitary accumulations around the walls.

In the accompanying drawings, Figure 1 is a perspective view, partly in section of a cast iron bath tub, embodying the invention. Fig.

2 is a transverse sectional View of the pre- 5 ferred construction of hollow rim. Fig. 3 is a transverse sectional view of a modified form of hollow rim.

The hollow metallic rim, A, is particularly adapted for application to cast iron bath tubs of'the'forin shown at B in the drawings, or ot' 5o any other approved form, such tubs being cast with a narrow flange C, around the mouth or upper edge of the tub and projecting outwardly. This 4flange forms a support for and means of attachment -ot" the rim, which is usually of wood, oiled and varnished, but which forthe purposes of the presentimprove. ment is made of metal in the form ot a flattened tube, ora tube conforming in cross section to the shape usuallygiven to the Wooden 6o rim. 'lhe hollow rim is made by taking a sheet or sheets of brassor other suitable metal, passing it lengthwise through dies or subjecting itto the action of a press or rolls, bending it over. to the shape required and brazing the edges together as shown at a in Fig. 2. A dependinglip or bead is formed at.

b and this is pierced at intervals with small holes ci, d, through-which the water entering the rim from the water supply, is allowed to zo iiow down over the wallsof the tub. In the form shown in Fig.2 the hollow rim is formed with two depending flanges, b, b are formed, the outer bead b being used to conceal the outer edge ofthe flange ofthe tub. In the modified form illustrated in Fig. 3, there is but. onebead, 'L'. e. on the inner side, the sheet; from which the rim is formed being curved over the brazed joint or seam g, and bent downward a suiiicient. distance to hide the 8o fiange of the tub. The hollow rim is secured tothe Hange of the tub by small bolts and nuts h or in any other convenient manner.

I-I designates a hollow casting to which the ends of the tubular rim are secured and which serves as a means for the connection of the hot and cold watersupply pipes or pipe. This casting may be arranged at the end or side of the tub as may be desired.

Having described this invention, what is 9c claimed, and desired to be secu red by Letters Patent, is-

1. The combination with a bath tub, of a hollow metallic rim, connected to the water supply, perforated around its under and inner side and having a dependinglipor flange embracing the edge of the tub.

2. The combination with a bath tub, ofva perforated at intel-"vals and connected to the water supply, substantially as described.

In testimony whereof we ailix our signatures in presence of two witnesses.
